Explore the advanced analytics platform, Part 8: The Information Governance Model
Big data lakes are ingesting large volumes of internal and external data. Without proper governance, these data lakes risk becoming data marshes. These marshes might contain disorganized, low quality data that can corrupt the entire data repository, leading to confusion and chaos. This tutorial proposes a set of processes, and a tool set, to structure the data and implement information governance in the big data lake. The result is improved trustworthiness and organization of the information that is contained in the data lake. This underlying information governance architecture is embedded in the Advanced Analytics Platform.

Autoscale your database with ScaleBase for zero downtime of cloud applications
Clouds are becoming the core IT infrastructure for hosting and delivering web scale, enterprise-grade, highly elastic applications in a "use and pay" fashion. Start-ups as well as established business behemoths face tedious challenges with highly scalable, mission-critical applications. Back-end databases are the essential module for every type of transactional, interactive, and collaborative application. Data storage and management systems must be cognitively adaptive to fulfill emerging needs. However, traditional databases are insufficient for cloud-scale applications. ScaleBase is an innovative, highly scalable, zero downtime, cloud-scale database solution. This article describes how to prepare and migrate ScaleBase to IBM SoftLayer. A sample application shows how ScaleBase functions in an online, off premise, on-demand cloud environment.

Centralize logs for IBM Bluemix apps using the ELK Stack
IBM Bluemix, IBM's next-generation cloud platform, enables developers to quickly build, deploy, and manage cloud applications. Due to its cloud nature, Bluemix does not automatically persist application log files. However, it does let developers drain their logs to external log management services. This feature, coupled with the components of the ELK Stack (Elasticsearch, Logstash, and Kibana), not only provide developers a centralized location for persistent logs, but also enables them to run analytics on and visualize the log data. This article is targeted for intermediate developers who are familiar with Bluemix and have a basic familiarity with Linux. It provides a brief background on the ELK Stack and then walks you through the process of installing and configuring the components.
